S2MSP vs ThreatScoopOnionChat
Side-by-side comparison of two open source alternatives
S2MSP
As Google strongly restricts the use of SMS permissions for applications in the Play-Store, S2MSP provides an API for third party applications to send and receive SMS to specific phone numbers via a secure SMS proxy.S2MSP acts like a local firewall for SMS communication.Each application that wants to send/receive SMS to a phone number can register itself on S2MSP. S2MSP asks the user for permission, whether the requesting application is allowed to send/receive SMS from and to the requested phone numbers or not.All SMS exchanged with third party applications are strongly encrypted.S2SMP itself requires SMS permissions (SEND_SMS and RECEIVE_SMS) from the Android system and will request these permissions upon startup. S2MSP does not need any other permissions. This ensures the integrity and security of S2MSP.The API to integrate a third party application with S2MSP is available in Maven-Central.
ThreatScoopOnionChat
# ThreadScoopOnionChat This version is a fork from " https://github.com/session-foundation/session-android ", enfocado en la privacidad. ## How Did ThreadScoopOnionChat Come About? I have always been a fan of privacy and security in communications, and I am constantly researching potential security breaches in messaging applications. ThreadScoopOnionChat emerged after the analysis of this blog "https://soatok.blog/2025/01/14/dont-use-session-signal-fork/", in which several aspects are described as to why using Session is not recommended, and I wondered how it is possible that a foundation focused on privacy—with the grants and support it receives—has not been able to improve this protocol. I still do not understand the answer, since my resources are much smaller than those of a foundation compared to that of a person who is simply a fan of privacy and security. In this blog, certain problems were described: 1> "https://soatok.blog/2025/01/14/dont-use-session-signal-fork/#insufficient-entropy-ed25519" 2> "https://soatok.blog/2025/01/14/dont-use-session-signal-fork/#in-band-negotiation" 3> "https://soatok.blog/2025/01/14/dont-use-session-signal-fork/#public-keys-aes-gcm" This is a forked version privacy focussed from Session.
